If/When I am really hungry (literally- have great hunger)... (It's a fragment.)
The "am" can mean several different things depending on what follows (it can mean at, on, in, by, most, etc.). "Ich habe" means "I have."
ich habe kein Geld = I have no money
I don't like you.
Angst means anxiety, fear. "Ich habe Angst" means "I am scared", "I´m afraid of...". "Habe" is a form of "haben", which means "to have" in English. So, literally the sentence "Ich habe Angst" translates as "I have fear".
It translates "I've lost my wristwatch."
Correctly conjugated it should be "ich habe." This means "I have".
It means: "What I've really learned at school".
ich habe = I have nor is not a German word
"Ich brauche dich" is "I need you" in English.
I am hungry. Literally 'I have hunger'.
Most of the time it means "I have understood nothing" or simply "I understood nothing".
I have my family very much. It's not a proper sentence.
